Dynamic HTHP Filter Press, Model DHF-01

The Dynamic HTHP filter press measures filtration volume and cake building properties under varying downhole conditions.

The industry’s only true dynamic filtration system for conducting filter cake formation and permeability analysis for drilling fluids optimization

The Dynamic High Temperature High Pressure (HTHP) filter press measures filtration volume and cake building properties under varying downhole conditions. A motor driven shaft fitted with propellers turns at varying speeds inside a standard 500 mL HTHP cell. RPM settings from 1 to 1600 RPM impart laminar or turbulent flow to the fluid inside the cell. By varying the shaft length, the shear stress may be increased or decreased. The power is driven to the stirring shaft by a timing belt that is easily accessible for quick adjustment and removal.

Other features include a variable‐speed motor controlled through a SCR controller. RPM is indicated on a digital tachometer. The test procedure is exactly the same as that in the conventional HTHP filtration test. The only difference is the fluid circulates inside the cell while filtrate is being collected. Since the filter medium is conventional disk material, the results are fully comparable with those of other laboratories or for comparing historical trends.

Competitive Advantage:

The Dynamic HTHP Filter Press’s unique design is touted for providing you with the most representative data possible.

The ability to vary the propeller used, the length of the shaft and the RPM allow you to more accurately resemble the wellbore.

Because of it’s flexibility, Dynamic HTHP Filter Press is very useful for a variety of applications, including drilling fluids, drill‐in fluids, and completions.

In addition, Dynamic HTHP Filter Press is very economically priced compared to competitive models.
